It would be weird to expect young children to sit in long Zoom meetings. Are people actually doing that? I have 3 kids, the oldest two are elementary-school age. So far virtually none of their online learning has been video conference based. The younger one would sometimes do Zoom calls with his pre-k class at the end of last year, but it was just a few minutes to see his friends and sing some songs, not really about trying to learn academically. Both of them have online based activities assigned by their teachers, though. They are self-paced, somewhat gamified learning platforms (kind of like, but not actually, ABCMouse.) It's at most 1 hour a day for the younger one and maybe 2 for the older one, including 20-30 minutes of reading time. This year they are both doing in person classes two days a week and the rest from home, but again no Zoom meetings. The teachers are teaching the other half of the class on the other two days so couldn't really do in-person stuff anyway.
